Abstract :
A wideband mm-wave active balun consisting of a CB/CE input and fully-differential second stage is described. In the 54-59GHz passband, measured amplitude and phase errors are 0.7±0.5dB and ±5°, respectively. Measured |Sn| is <;-18dB from 50-65GHz, and cascoding is used to realize better than 39dB reverse isolation overall. The 0.2×0.19mm2 balun is implemented in 130nm SiGe-BiCMOS, and consumes 10.4mW from a 2V supply.
